You can think of aDynamic Routing Gateway (DRG)as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region.

For example, if you use anIPSec VPNorOracle Cloud Infrastructure FastConnect(or both) to connect your on-premises network to your VCN, that private IPv4 address traffic goes through a DRG that you create and attach to your VCN. For scenarios for using a DRG to connect a VCN to your on-premises network, seeNetworking Scenarios. For important details about routing to your on-premises network, seeRouting Details for Connections to Your On-Premises Network.

Also, if you decide to peer your VCN with a VCN in another region, your VCN's DRG routes traffic to the other VCN over a private backbone that connects the regions (without traffic traversing the internet). For information about connecting VCNs in different regions, seeRemote VCN Peering (Across Regions).

Web Application Firewall (WAF) is the Oracle Cloud Infrastructure service that is designed to protect web applications from various types of malicious attacks, such as SQL injection and cross-site scripting. WAF is a cloud-based service that inspects incoming web traffic and blocks any requests that are malicious or do not comply with predefined rules. WAF helps users secure their web applications from common web exploits and application-layer attacks.

Oracle Cloud Infrastructure offers two distinct storage class tiers to address the need for both performant, frequently accessed 'hot' storage, and less frequently accessed 'cold' storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.

1) UseObject Storagefor data to which you need fast, immediate, and frequent access. Data accessibility and performance justifies a higher price to store data in the Object Storage tier.

2) UseArchive Storagefor data to which you seldom or rarely access, but that must be retained and preserved for long periods of time. The cost efficiency of the Archive Storage tier offsets the long lead time required to access the data. For more information, seeOverview of Archive Storage.

The Oracle Cloud Infrastructure Object Storage service is an internet-scale, high-performance storage platform that offers reliable and cost-efficient data durability. The Object Storage service can store an unlimited amount of unstructured data of any content type, including analytic data and rich content, like images and videos.

With Object Storage, you can safely and securely store or retrieve data directly from the internet or from within the cloud platform. Object Storage offers multiplemanagement interfacesthat let you easily manage storage at scale. The elasticity of the platform lets you start small and scale seamlessly, without experiencing any degradation in performance or service reliability.

Object Storage is a regional service and is not tied to any specific compute instance. You can access data from anywhere inside or outside the context of the Oracle Cloud Infrastructure, as long you have internet connectivity and can access one of theObject Storage endpoints. Authorization and resource limits are discussed later in this topic.

Object Storage also supports private access from Oracle Cloud Infrastructure resources in a VCN through aservice gateway. A service gateway allows connectivity to the Object Storage public endpoints from private IP addresses in private subnets. For example, you can back up DB systems to an Object Storage bucket over the Oracle Cloud Infrastructure backbone instead of over the internet. You can optionally use IAM policies to control which VCNs or ranges of IP addresses can access Object Storage. SeeAccess to Oracle Services: Service Gatewayfor details.

Object Storage is Always Free eligible. For more information about Always Free resources, including additional capabilities and limitations, seeOracle Cloud Infrastructure Free Tier.

The following list summarizes some of the ways that you can use Object Storage.

Oracle Cloud Infrastructure Marketplace is an online store that offers solutions specifically for customers of Oracle Cloud Infrastructure. In the Oracle Cloud Infrastructure Marketplace catalog, you can find listings for two types of solutions from Oracle and trusted partners: images and stacks. These listing types include different categories of applications. Also, some listings are free and others require payment.

Images are templates of virtual hard drives that determine the operating system and software to run on an instance. You can deploy image listings on an Oracle Cloud Infrastructure Compute instance. Marketplace also offers stack listings. Stacks represent definitions of groups of Oracle Cloud Infrastructure resources that you can act on as a group. Each stack has a configuration consisting of one or more declarative configuration files. With an image or a stack, you have a customized, more streamlined way of getting started with a publisher's software.
